olfactory bulb neurogenesis

The Science Explained In the rodent brain, the subventricular zone (SVZ) generates thousands of new olfactory bulb neurons every day. Three years ago, a paper in Nature announced the existence of adult neural stem cells in the SVZ lining the lateral ventricles of the human brain, but the authors could find no evidence of a pathway linking the SVZ to the olfactory bulb as in the rodent brain

This is an advance summary of a forthcoming article in the Oxford Research Encyclopedia of Neuroscience. Please check back later for the full article.In adult mammals, the olfactory bulb and the hippocampus are the regions in the brain that undergo continuous

The initial processing of olfactory information (“olfactory computation”) by the brain is performed in the olfactory bulb. Strikingly, even in adult animals the largest population of neurons in this network is undergoing persistent turnover through neurogenesis and

Inhibitory interneurons of the olfactory bulb are subjected to permanent adult neurogenesis. Their number is modulated by learning, suggesting that they could play a role in plastic changes of the bulbar network associated with olfactory memory. Adult male C57BL/6

The rostral migratory stream (RMS) is the main pathway by which newly born subventricular zone cells reach the olfactory bulb (OB) in rodents. However, the RMS in the adult human brain has been elusive. We demonstrate the presence of a human RMS, which is

Adult neurogenesis is the process in which neurons are generated from neural stem cells in the adult. This process differs from prenatal neurogenesis. In most mammals, new neurons are born throughout adulthood in two regions of the brain:[3] The

Olfactory bulb neurogenesis is well documented in animals, but the extension to which it occurs in humans has remained controversial . In a recent study, Bergmann and coworkers [35] quantified the number of new cells in the olfactory bulb by measuring 14 C in the DNA of humans who were born during the 1950 s, when atomic bomb tests were performed at the earth’s surface.

INTRODUCTION The olfactory bulb (OB) is one of the regions in the mammalian forebrain in which neurogenesis persists throughout life. During both development and adulthood the expression of specific transcription factors (TFs) defines different progenitor territories

Olfactory neurogenesis is particularly suited to approach these late steps in neuronal differentiation. Here, stem cell populations first located in the ventricular zone and after the establishment of an ependymal layer positioned in subventricular zone (SVZ)

Adult neurogenesis in the olfactory bulb is influenced by behaviors related to functions of the olfactory bulb, but the newly generated cells in turn influence those same behaviors. Lledo argued that adult olfactory neurogenesis in mammals is flexible and thus

The olfactory ensheating cells, which are specialized olfactory glial cells, enclose the newly formed axons and help to direct them through the cribriform plate to the olfactory bulb. Because the olfactory epithelium is readily accessible from its location in the nasal

Neurogenesis in the rat primary olfactory cortex 253 cortex (Fig. 3), the percentage of labeled cells in the intermediate area tended to be slightly higher than the percentage of labeled cells either above or below this area. However, variability

The sense of smell depends on neurons in the olfactory epithelium to perceive chemical scents. Each neuron specializes with one receptor. Hanchate et al. now show that the one-for-one relationship is not as simple as thought. As new neurons develop to replenish the olfactory epithelium, they initially express several different alleles of olfactory receptors. Then, as each neuron matures, they

The reshaping and decorrelation of similar activity patterns by neuronal networks can enhance their discriminability, storage, and retrieval. How can such networks learn to decorrelate new complex patterns, as they arise in the olfactory system? Using a computational network model for the dominant neural populations of the olfactory bulb we show that fundamental aspects of the adult

Abstract The properties and fate of the cells of the subependymal layer of the anterior lateral ventricle and its rostral extension into the olfactory bulb were examined. In one experiment, histological analysis was made of this structure in a large group of rats, ranging

Normally, the new neurons made in that zone migrate to the olfactory bulb a specialized structure involved in our sense of smell. Evidence demonstrates that deficits in the sense of smell and neurogenesis occur early in neurodegenerative diseases.

How new neurons are produced in parts of the adult brain Neurogenesis occurs during embryonic development, and also in parts of the adult brain following birth. This process, known as adult neurogenesis, was first recognised in the 1960s, although it took until the 1990s for the field as a whole to accept that neurogenesis in adult animals could play a substantial role in brain function.

New neurons are generated in the adult brain from stem cells found in the subventricular zone (SVZ). These cells proliferate in the SVZ, generating neuroblasts which then migrate to the main olfactory bulb (MOB), ending their migration in the glomerular layer (GLL

While insulin‐like growth factor‐I (IGF‐I) supports neuronal and glial differentiation in the CNS, it is largely unknown whether IGF‐I also influences neuronal migration and positioning. We show here that the pattern of olfactory bulb (OB) layering is altered in Igf‐I −/− mice. mice.
